novel construction hereinafter. specied andv claimeda ne object of this invention is to provide an improved body-bolster which Awill permit the removal and renewal of the draftsills Aor center-sills without removing the bolster from the car, or in any way disturbing the members of the bolster which are secured to the undert'rame of the car.

AnotherV object is to provide a metallic carbolster provided with a recess in its under side, .and a combined center bearing and compression block adapted to :be located within said recess to completely lill the same together ywith the draft-sills or center-sills which extend through the recess.

Another object is to provide a bolster witlrfa recess to receive the central longi tudinalmembers of thel car in such a position.that they-can support'the draft appliances without any intermediate connections, land thereby receive all the strain. directly.

Figure 1, is a top plan View of my body bolsterfas applied. to a car underframe hav ing. its central longitudinal members of woodg Fig. 2, is a sectional elevation there-A of on line 2-2; Fig. 3, 1s a sectlonal elevation of Fig. 1, on line .2-2, rolled ychannel center longitudinal members being substituted for wooden' ones Fig. 4, is an end elevationll of the. combined! center bearing and compression-block, shown in Figs.. 1 and 2, and-Fig. 5, is an end elevation of the combined center bearing and compression block shown in Fig. 3.

The main bodyof the bolster. consists ot the top tie "member, 1, in the form of a flat plate, tying together, through ftheir upper flanges, 2, the two metallic transoms' or Vdiaphragms 3, to which it issecured.

4 indicates the lower members, forming the main body of the bolster, which extend outwardly and upwardly as shown, and are secured to the lower flanges, 5 of the me tallic transoms or diaphragms 3.

Between the inner ends of the transoms or dlaphragms 3, is a recess and the said inner ends of Ithese members are connected with .the tie member 1 by means of the web plates 6, and flanges 2,`of-said transom or diaphragms, 3. -The inner ends of the members 3, are provided with flanges 7 for connection to the center sills 8, and the outer ends thereof are provided' with flanges/9, for connection to the side membersof the car underframe, not shown in the drawings, but which may be of any suitable form.

As clearly shown in Figs. 1 and 2, the draft sills or center sills 8 are preferably formed, of wood, althoughthey may be' formed of channel members as shown in Fig. 3, or of any 'other suitable section.

B v referring to Figs. `1 and 2, it will be seen that after the longitudinal members 8, are in position, there is a considerable space between saidimembers, .which I lill by a combined, center plateV and compression block formed as a single casting and consistingof the top 10 and the bottom 11, connected r.by

the annular. .member 12 forming an opening for the king bolt, and lan'ges :13. The center bearing 14, Iis formed integral with the under-side of the bottom member 11. The bottom member 11, is extended and recessed at its ends at 15,.in such a manner that they` may be secured by suitable4 means 16, to the lower members 4, and to the lower tlanges.5, of the transoms or diaphragms The top -1'0 of the combined center plate and .com pression block is also-secured by suitable means 17 to the top tie member 1. l`Thelongitudinal members S are secured in posit-ion by bolts or other suitable means passing throughthe lianges 7 of members 3, the flanges 13 of the Combined center plate and compression block, andalso the said members 8; anges 13 being extended to a sufficient extent, as shown in Fig. 4, to admit of the insertion of a sufiicient number of bolts or other securing means. .When the combined fcentery fplate and compression-block is thus secured in position 1t forms a connection between the 4ends Iof the bolster, thereby preventing any downward. tendency of the ends, which might; occur were the central space 4left unfilled, In addition to serving as the compression-,block to strengthen the bolster and uphold the ends thereof, it forms 'a center plate or bearing adapted to rest upon the center bearing of the truck bolster `and to receive the king bolt, whereby the body of the car is held on the truck.

In Fig. 3 is shown a modification of my invention in which channel beams are substituted for the wooden beams shown in Figs. 1 and 2. In this modification the vertical webs of the channel beams are secured directly to the flanges 7 of the members 3.

' When it is necessary to remove or renew i' the longitudinal members 8, they can be taken out by simply removing the securing.

means 7, 16, and 17. The combined center plate and compression block also the longitudinal members 8 can then be lowered and removed. New longitudinal members can then be inserted in the recess, and the combined center plate and compression block and securing means replaced, without hav# ing to disturb any of the other component members of the body-bolster.

Having .thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is y 1. In a body bolster, the combination with -the center sills, of a pair of flanged transoms disposed back to back and spaced apartl on opposite sides of said center sills, a tension plate secured to the upper flanges of theV t-ransoms and passing across the center sills, a center bearing member having a projection extending upwardly between the center sills to the tension member and secured thereto. f

2.
